Book Description
Recent advances in the development of organic mixed ionic/electronic conductors (OMIECs) have paved the way for novel applications that harness these materials' ability to effectively transduce ionic fluxes into electronic signals, such as in the fields of biosensors and neural interfaces. With the modulation taking place throughout the bulk of the material, such organic electrochemical devices offer a volumetric advantage over their inorganic counterparts, with high-transconductance operation feasible even at low operating voltages. This unique mode of operation may be exploited by a wide variety of applications, some yet unexplored. However, while some classes of organic semiconductors have seen tremendous success in market realization, such as the multi-billion-dollar OLED industry, integration of OMIEC semiconducting polymers systems into traditional fabrication processes remains a difficult technological challenge. In this work, I lay out novel strategies to allow for the nanofabrication of previously unattainable organic electrochemical devices, as well as the characterization thereof. The first part of this dissertation provides an introductory background to both organic electrochemical materials and devices, as well as nanofabrication, with a third chapter discussing the work done to bridge the gap between the two. In the second part, I turn to focus on specific applications of nanofabricated organic electrochemical devices, first exploring the properties of an organic electrochemical transistor (OECT) comprised of a lithographically patterned semiconducting polymer and a non-aqueous electrolyte. The remainder of the dissertation focuses on utilizing OMIEC materials for acceleration of artificial neural networks, discussing the characterization and fabrication strategies developed for realizing submicron-scale, MHz addressable, fully encapsulated organic ECRAM devices.

Book Description
"To develop devices based on conducting polymers for the benefit of humanity - such as, for example, artificial muscles and lab-on-a-chip diagnostics - we require the ability to reliably fabricate and understand these materials at the micro and nano scales. In this thesis I present research towards that goal, by developing novel experimental techniques for the fabrication and characterization of poly(3,4-ethylenedioxythiophene) (PEDOT) and polyaniline (PANI), two prominent conducting polymers. Many of the strategies presented herein are based on miniaturized pipettes driven by scanning ion conductance microscopy (SICM), with some complementary techniques also explored. I begin this thesis work by describing the construction of a low-cost SICM, and its further development to include novel modifications that enable its application to conducting polymers. One of these is the first SICM-based measurement of the ion flux that underpins PEDOT actuation, an important issue in artificial muscles and micropumps. Another is the first electrochemical fabrication of microscale PEDOT and PANI structures and arrays. This approach is then extended to map the activity of the resulting microstructures using modified SICM-based protocols. For example, it is demonstrated that pipette-defined cyclic voltammetry can yield highly localized characterization of microstructures, an important topic for biosensor applications. Indeed, this technique is demonstrated herein for the characterization of a PEDOT nanowire based DNA sensor. Finally, complementary studies on PANI nanostructures are also presented. The first synchrotron radiation studies of PANI nanotube self-assembly is undertaken, revealing crystallinity at critical early stages of the reaction. Furthermore, focused ion beam and electron microscopy techniques are used to perform studies on the electrical properties on individual PANI nanostructures. Both of these have relevance for potential integration with the aforementioned SICM-based techniques. Altogether, these methodological innovations and resulting findings represent significant advances in the burgeoning field of pipette-localized conducting polymer fabrication and characterization. I conclude the thesis with implications discussed for future fundamental research and device applications".

Book Description
In this thesis, a series of novel organic conducting polymers have been synthesized using alternative methods based on electrochemical techniques, which have allowed to broaden the knowledge in the field of the characterization by means of topological, spectroscopic, electrochemical and structural techniques. Among the variety of synthesis techniques of conducting polymers, layer-by-layer (LbL) has been one of the most important to build multilayered systems. Thus, in this thesis the LbL has shown to be an excellent procedure to explore new applications in the field of energy storage using conducting polymers. On the other hand, recently, the influence of new sustituents on functionalized conducting polymers has been proved to modify the structural, optical and physical properties of conducting polymers. Within this context, synthesis of novel functionalized conducting polymers bearing strong electron-withdrawing sustituents such as cyano group or halide atoms have been widely studied and characterized throughout this thesis. The presence of these substituents have emerged as promising candidates in the field of chemical sensors and electrochromic devices. Although the functionality of polymers or the development of new techniques are excellent procedures to synthesize and to develop new properties on the field of conducting polymers, it is worth mentioning that the substrate plays a crucial role on the electrochemical field. Accordingly, the substrates can also modify and change the properties of conducting polymers during the electropolymerization process. In this way, different substrates were employed in this work with the aim of achieving new applications in the field of corrosion inhibitors and as supercapacitors. Supercapacitors as energy storage device has been an outstanding application during this thesis. Thus, the field of nanotechnology has taken an important part in this thesis through development and design of promising hybrid nanocomposites based on conducting polymers and clay with technological applications and interesting optoelectronic properties. The contribution of theoretical techniques based on quantum mechanical calculations have allowed to predict some electronic and structural properties of conjugated polymers, which could be corroborated experimentally. The quantum mechanics is a useful tool to check experimental results and to understand mechanisms not fully understood at experimental level. Therefore, theoretical calculations have provided promising information to obtain new insights in the field of conducting polymers.

Book Description
Nanotechnology is a 'catch-all' description of activities at the level of atoms and molecules that have applications in the real world. A manometer is a billionth of a meter, about 1/80,000 of the diameter of a human hair, or 10 times the diameter of a hydrogen atom. Nanotechnology is now used in precision engineering, new materials development as well as in electronics; electromechanical systems as well as mainstream biomedical applications in areas such as gene therapy, drug delivery and novel drug discovery techniques. This book presents the latest research in this frontier field.
